I have Nokia sv40 Cellphone which I want to use as a dial up modem to connect to internet. I connected to my system, Ubuntu detected it and opened up a wizard to complete the installation and setup of the connection. I completed it successfully. Now the problem is that I cannot connect to internet using my Nokia. I checked settings from control center and found out that Mobile Broadband is disabled, I tried to enable it but it doesn't. Flight Mode is off. What should I do to fix this.
